DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, wherein like numerals refer to like partsthroughout the several views, FIG. 1 illustrates a portable containmentsystem 30. The portable containment system 30 includes a flexible bag32, a plurality of pedestals 34, and at least one grate 36. Asillustrated, the grate 36 supports a container 38. Further, a railing 42can be attached to the pedestals 34.

With reference to FIGS. 1-3 and 7, the flexible bag 32 is formed of aflexible fabric or sheet that defines an integral fluid-tight orleak-proof structure. Initially, it is noted that the term ‘leakage’could include solids or liquids. The flexible bag 32 includes a baginterior 44 that is defined by the bag sidewall 46. The bag sidewall 46includes a bag sidewall interior surface 48 and a bag sidewall exteriorsurface 52, which is opposite the interior surface 48. The flexible bag32 contains any leakage that may occur from the container 38 that haspassed through the grate 36.

As illustrated, the flexible bag 32 also includes a bag bottom 54 thatis opposite the grate 36. For reference, the bag sidewall 46 defines anopening that receives the grate 36. The bag bottom 54 includes a bagbottom interior surface 56 and bag bottom exterior surface 58, with thebag bottom exterior surface 58 being opposite the bag bottom interiorsurface 56. As illustrated, the bag 32 receives the plurality ofpedestals 34 and contains leakage from the container 38. The interiorsurfaces 48, 56 of the flexible bag 32 face the plurality of pedestals34.

With the continued reference to FIGS. 1-3, the grate 36, which couldalso be referred to as a support deck, includes an upper grate surface62 and a lower grate surface 64 and is of a generally rectangular shape.The grate 36 can be made from injection-molded or rotationally moldedplastic or structured foam. The lower grate surface 64 is opposite theupper grate surface 62. The grate 36 also includes a side grate surface66 that faces the bag sidewall 46. The grate 36 also defines a pluralityof drain holes 68 that allow leakage from the container 38 to passtherethrough for collection in the bag 32. Further, the grate 36 servesto support the container 38. While illustrated as being a plurality ofgrates, it will be appreciated that the grate 36 could be a single grateor a plurality of grates.

With particular attention to FIGS. 2-3 and 7, the pedestal 34 is shown.The pedestal 34 includes a pedestal top wall 72 that has a generallyplanar face that faces toward the grate 36. The planar face allows for astable interface between the pedestals 34 and the grate 36. Thepedestals 34 are hollow, which allows them to be stacked on atop theother in nested fashion, much like disposable drinking cups (open enddown). This allows for the pedestals 34 to be shipped and stored in acompact condition. The pedestal wall 74 can define a plurality ofgrooves 76 that extend in a generally vertical direction. The grooves 76increase the strength of the pedestals 34 and also allow air to enterbetween the pedestals 34 when they are being separated from each other(i.e., un-nested), making separation easier

As shown in FIGS. 2-3, the pedestals 34 are single-piece, unitaryconstruction, which can be made from injection-molded or rotationallymolded plastic or structured foam. The pedestals 34 may reduce incross-sectional size as they extend from the bag bottom 54 toward thegrate 36 so as to have a tapered shape. This tapered shape allows a widebase to increase stability with a smaller top to reduce the number ofdrain holes 68 that are obstructed by the pedestal 34. It will beappreciated that additional pedestals could be used to support the grate36 at positions other than the perimeter (i.e., under the center of thegrate). The pedestals 34 illustrated in FIGS. 1-3 and 7 aresingle-piece, unitary pedestals.

The pedestals 34 include a plurality of primary projections 78 thatextend from the planer face of the top wall 72 toward the grate 36 so asto be received alongside the grate 36. As illustrated, the primaryprojections 78 have a circular cross-section. However, it will beappreciated that other shapes are contemplated. The pedestals 34 canalso include a plurality of secondary projections 82 that extend fromthe planer face of the top wall 72 toward the grate 36. Although thesecondary projections 82 are shown as having a circular cross-section,it will be appreciated that other shapes are possible. Specifically, anyshape that allows the secondary projections 82 to be received in thedrain hole 68 of the grate 36 is possible. As illustrated, the primaryprojections 78 are disposed around a perimeter of the top wall 72 so asto at least partially surround the secondary projections 82. Thisarrangement helps to keep the grate 36 secured to the pedestal 34.

Further, the secondary projections 82 define a secondary projectionlength as they extend from the top wall 72 toward the grate 36 just asthe primary projections 78 define a primary projection length as theyextend from the top wall 72 toward the grate 36. As illustrated, theprimary projection length is greater than the secondary projectionlength. This difference in projection length between the primaryprojections 78 and the secondary projections 82 allows for the grate 36to be indexed to the pedestal 34 with the primary projections 78 whilestill providing positive engagement between the grate 34 and thesecondary projections 82.

It will be appreciated that the primary and secondary projections 78, 82described hereinabove could be part of the grate 36 instead of thepedestals 34. Specifically, alternate projections could downwardlyextend from the grate 36 toward the pedestals 34 so as to providesimilar engagement between the grate 36 and the pedestals 36 aspreviously described. It will also be appreciated that if alternateprojections extending from the grate were utilized, that the pedestalscould include at least one bore or indentation provided in the top wallto receive the respective projections. Further, it will be understoodthat a combination of projections extending from the grate andprojections extending from the pedestal could simultaneously be employedwithout departing from the scope of the invention.

With reference to FIGS. 1-2, a plurality of posts 84 are shown. Theposts 84 each include a first end 86 and a second end 88, with thesecond end 88 being opposite the first end 86. The plurality of posts 84are joined to one another by a connecting rail 92 that attaches near thefirst end 86 of each of the posts 84. Further, the posts 84 can beattached to the pedestals 34 at the second end 88 of the respectiveposts 84. As such, the second end 88 of the respective post 84 canreceive at least a portion of the primary projection 78 of the pedestal34. Therefore, the posts 84 can be mounted to the pedestal 34 withoutthe use of additional hardware, thereby minimizing cost and simplifyingassembly of the system.

With reference to FIGS. 4-5, an alternative containment system 90 with aa composite pedestal 94 is shown. The composite pedestal 94 can be madeof the same materials as the pedestal 34. Further, the compositepedestal 94 can also be hollow. The composite pedestal 94 can include anupper pedestal member 96 with a sidewall 98 and a top wall 102. Thecomposite pedestal 94 can also include a lower pedestal member 104 witha sidewall 106 and a top wall 108.

The lower pedestal member 104 can include a raised rim 112. This raisedrim 112 can be used to prevent lateral disengagement between the upperpedestal member 96 and the lower pedestal member 104. The lower pedestalmember 104 can also include a base ring 114. This base ring increases ageneral footprint of the pedestal 94 to increase stability while beingreceived with the bag 32.

As illustrated, the lower pedestal member 104 can also include a bead116 and the upper pedestal member 96 can include a column 118. The bead116 and the column 118 cooperate to assist when the respective pedestalmembers 96, 104 are respectively nested, similar in function to thegroove 76. As shown, a block 122 may be used as an interface between thegrate 36 and the composite pedestal 94. The block 122 may optionally beused to adjust an overall height of the grate 36. As shown in FIG. 5,the composite pedestal 94 includes primary projections 78 and secondaryprojections 82 as like the pedestal 34.

The composite pedestal 94 allows for customization. Specifically,depending upon the particular needs, the end user could use only upperpedestal member 96 or the lower pedestal member 104 to support the grate36. Alternatively, the end user could use both the upper pedestal member96 and the lower pedestal member 104 to form taller pedestal structures.Thus, for small volume containment needs or in instances when the grate36 is going to be used to store a drum or container in a workstationconfiguration, a shorter single pedestal member could be used. However,in instances when a pallet of drums was going to be stored and thevolume of potentially leakable materials is greater, tallermulti-component pedestals could be used.

As illustrated in FIG. 5, the bag 32 can include a pocket 124 thatreceives the primary projection 78 so as to attach the bag 32 to thepedestal 34, 94. Specifically, at least one of the primary projections78 can at least be partially inserted through the pocket 124. The pocket124 may be made of the same or similar materials as the bag 32.Alternatively, the pocket 124 may be made of other materials thatprovide sufficient strength to connect the bag 32 to the pedestal 34.Further, the pocket 124 may be integral to the bag 32 or a separatecomponent.

With reference to FIG. 6, an alternate containment system 120 is shown.The bag 32 can include a sidewall flap 126. The sidewall flap 126 atleast partially extends onto the upper grate surface 62 of the grate 36.The sidewall flap 126 may be of the same material and construction asthe bag sidewall 46. The sidewall flap 126 may be affixed to the grate36 with adhesive tape 128. This tape 128 may be used solely to attachthe bag 32 to the pedestal 34, 94 or in addition to other attachmentmethods.

With reference to FIG. 7, an alternate containment system 129 is shown.The alternate containment system 129 utilizes the bag 32 and pedestal 34to contain any leakage that has passed through the drain holes 68 of thegrate 36. However, the alternate containment system 129 also includes amounting member 130. The mounting member 130 is disposed between thepedestal 34 and the grate 36 to ensure that the bag sidewall 46 of thebag 32 remains sufficiently vertical so as provide an adequate volumefor capturing the leakage. As illustrated, the mounting member 130includes mounting holes 131 that receive the primary projections 78. Themounting member 130 may be integral to the bag 32 or may be a separatecomponent that is connected to the bag 32. As such, the mounting member130 may be made of any material that provides sufficient strength toretain the bag sidewall 46 in a generally upright position. Because themounting member 130 is disposed between the pedestal 34 and the grate36, the mounting member 130 is exposed to downward force due to theweight of the container 38 (i.e., a compressive force between thepedestal 34 and the grate 36). As such, the connection strength betweenthe bag 32 and the pedestal 34 improves as the weight of the container38 on the grate 36 is increased.

With reference to FIGS. 8-12, post brackets are shown. The post bracketscan be used to mount the post 84 to the grate 36. The post brackets canbe used in addition to or in place of mounting the post 84 to theprimary projections 78. Further, the post brackets can be made of anynumber of materials that provide sufficient strength and rigidity tosupport the post 84 as will be described in more detail hereinafter.

With reference to FIGS. 8-10, a clamp 132 is used as a post bracket. Theclamp 132 includes an upper wall 134, a lower wall 136, and a connectingwall 138. The upper wall 134 defines a posthole 142. The grate 36 isdisposed between the upper wall 134 and the lower wall 136. Because ofthe shape of the clamp 132, the clamp 132 can be securely connected tothe grate 36, while still permitting removal of the clamp 132 from thegrate 36 when desired.

In particular, the posthole 142 receives the post 84 to allow for easyattachment of the post 84 to the grate 36. Specifically, the first end86 of the post 84 is vertically spaced from the grate 36 a distance thatis greater than a vertical distance between the second end 88 of thepost 84 and the grate 36. The bracket can further include a retentionmember 144 that extends from the upper wall 134 toward the lower wall136 so as to be received at least one of the drain holes 68. Theretention member 144 can have a square cross-sectional shape. This shapecomplements the shape of the drain hole 68 for sufficient engagement.The connecting wall 138 joins the upper wall 134 and the lower wall 136so that the post 84 is disposed between the connecting wall 138 and thegrate 36, thereby ensuring a sturdy connection.

With reference to FIGS. 11-12, an alternate bracket is shown as a clip146. The clip 146 can include an upper wall 148 and a lower wall 152. Apartition wall 154 joins the upper wall 148 and the lower wall 152together so that the partition wall 154 is disposed between the post 84and the grate 36. The upper wall 148 can also include a post aperture156 for receipt of the post 84. Further still, a post boss 158 canextend from the lower wall 152 toward the upper wall 148 so as to be inregistry with the post aperture 156 for engagement with the second endof the post 84. The post boss 158 provides additional stability to theconnection between the post 84 and the clip 146. The clip 146 can alsoinclude a retention projection 162 with an X-shaped cross-section. Theretention projection 162 extends from the upper wall 148 toward thelower wall 152 and is received in the drain holes 68 of the grate 36.The X-shaped cross-section of the retention projection 162 helps tominimize weight and material cost for the clip 146 while still providingsufficient engagement between the clip 146 and the grate 36.

With reference to FIGS. 13-16, an alternate containment system 164 isshown. The containment system 164 can include a first beam 166 and asecond beam 168. The beams 166, 168 can have a generally rectangularshape and be made of any number of materials. It is envisioned that thebeams 166, 168 be constructed of materials that are chemically inert andlightweight. However, other materials are possible and contemplated. Thefirst beams 166 are spaced from and oriented parallel to one another.Further, the first beams 166 each include a first beam top surface 172that faces the grate 36 and a first beam bottom surface 174 that isopposite the first beam top surface 172.

The second beams 168 are spaced from one another. As illustrated, thesecond beams 168 are oriented perpendicular to the plurality of firstbeams 166. However, it will be understood that the second beams 168could be oriented to the plurality of first beams 168 in alternativelayouts. The second beams 168 can each include a second beam top surface176 that faces the grate 36 and a second beam bottom surface 178 that isopposite the second beam top surface 176. The first beams 166 and thesecond beams 168 are disposed within the flexible bag 32 so that atleast one of the first beam top surfaces 172 and the second beam topsurfaces 176 contacts the grate 36 and at least one of the first beambottom surfaces 174 and the second beam bottom surfaces 178 contacts theinterior surface of the bag bottom 54 of the bag 32. The first beams 166and the second beams 168 can include beam fingers 182, 184,respectively. It will be appreciated that the first and second beams166, 168 could be spaced from one another greater than is illustrated soas to create a large void in a center of the assembly so as to create apicture frame type support. As the number of beams 166, 168 is reduced,the storage capacity of the bag 32 is increased.

As shown in FIG. 14, the flexible bag 34 may include a plurality ofyokes 186 that extend toward the interior of the flexible bag 32. Theyokes 186 may be made of the same or similar material as the bag 32.Alternatively, the yokes 186 may be made of any other material whileprovides sufficient strength to hold the bag 32 to the beams 166, 168when the bag 32 is full of leaked material. The fingers 182, 184 canremovably engage the yokes 186 of the bag 32 to attach the bag 32 to thebeams 166, 168.

With reference to FIG. 15, the first beam 166 and the second beam 168are shown in an exploded view. The first beam 166 can include a joiningchannel 188 and the second beam 168 can include a joining channel 192.The joining channels 188, 192 cooperate with one another to allowassembly of the first beams 166 and second beams 168 together in astructurally rigid configuration as illustrated.

With reference to FIG. 16, the first beam 166 is shown. As illustrated,the first beam 166 can include a tab 194 and slot 196. The tab 194 andthe slot 196 complement one another to allow shorter lengths of thefirst beam 166 to be combined to increase the overall length. It will beappreciated that a similar type of tab/slot layout could be used withthe second beam 168.

With reference to FIG. 17, an alternative spill containment system 198with an enclosure is shown. This system 198 includes a canopy 200. Thecanopy includes a frame 202 that supports a covering 204. The frame 202includes a plurality of upright members 206, linear connection members208, and curved connection members 210. These members 206, 208, 210 areheld together with a variety of connectors 212. The frame 202 cooperateswith the covering 204 to define a shell wall 216 and a shell top 218.Further, a shell door 222 is affixed to the shell wall 216 with a zipper224 to allow access within the canopy 200. Further, a document window226 can be used to retain various documents associated with thematerials located within the container 38. Further still, a tie down 228may be used to affix the shell wall 216 to the flexible bag 32. Finally,a mounting strap 232 can be used in conjunction with a stake 234 toaffix the containment system 198 to the ground or otherwise.

With reference to FIG. 18, an alternate containment system 236 with anenclosure is shown. This system 236 includes a rigid structure 238 withpanels 240 and a roof 242. Further, a tambour door 244 is attached tothe panels 240 with a rail arrangement to allow access to the container38 disposed within. Although not illustrated, it will be understood thatthe system 236 could also include a document window 226 for holdingdocuments.

As is considered apparent, the enclosures of FIGS. 17-18 allow thecontainer 38 to be located between the grate 36 and the enclosure (i.e.,canopy 200, rigid structure 238). The enclosure allows the containmentassembly to be used in outdoor applications. Further, rain and otherprecipitation does not enter into the flexible bag 32, but rather passesoff the enclosure and onto the ground. However, materials that haveleaked from the drums or contains stored on the grate 36 would becollected in the flexible bag 32. This ensures that the bag 32 does notbecome prematurely filled with material that does not need to becontained.

With reference to FIG. 19, an alternate portable containment system 246is shown. The system 246 can include a carrying handle 248 that isattached to the exterior surface 52 of the bag 32 at a plurality oflocations so as to define a loop. The loop is adapted to be ofsufficient size to allow for receipt of a human hand to aid in carryingthe system 246. Additionally, a plurality of packing straps 252 mayencircle the flexible bag 32. These packing straps 252 can be disposedso as to be spaced from and on opposite sides of the carrying handle248. The straps 252 ensure that all of the components remain within thebag 32 until deployment of the system 246 is needed.

Thus, the portable containment system 246 can be shipped or stored in acompact arrangement, not unlike a suitcase, which can be transported toan assembly location and assembled to form the containment system asillustrated in the other embodiments of the present application.Notably, the pedestals 34 and/or composite pedestals 94 could bedisposed within the bag 32 during shipment or storage or could beseparately located. Further still, the grate(s) 36 could be receivedwithin the bag 32 illustrated in FIG. 19 during shipment or storage.Thus, the bag 32 serves to contain the various components duringshipment/storage and also capture leakage from the container placed onthe grate during usage.

Additionally, advantages and modifications will readily occur to thoseskilled in the art.
